径流式小型水电站的运行优化

Operation Optimization for Radial Flow Type Small-sized Water Power Station

采用数值模拟计算方法对由两台水轮机并联运行而成的不同类型、不同尺寸的水轮机进行优化选型,并采用新开发的评估算法对海里水电站的运行状况进行了详细的模拟分析。结果表明,采用两台不同尺寸的水轮机,可以充分提高电厂的发电量和投资效益;使用不同尺寸的涡轮机可以提高电厂对季节性流量变化的响应能力。

In this paper,the author,by using numerical simulation calculation method,carried out optimizing and selecting type aiming at the parallel unit be composed of two water turbines with different types and sizes,and carried out in detail simulating and analyzing the operation situation for Haili water power station by using new developed evaluation method.The results show that using two different size water turbines can sufficiently increase the electric energy production and investment benefits,and using different size turbines can improve the responsive ability to seasonal discharge variation for the power plant.
